How do you import an object from another Blender file without losing textures?
Use a consistent set of materials for a Render engine.  Cycles Render or Blender Render.   Do not mix Cycles and Blender materials.

It appears you have tried to mix materials for the two different render engines.

If you are producing a single still photo you may be able to render one image as transparent .png file.  You may be able to render the album disc as a texture and apply it as .png which is render engine neutral.
